"They were hungry," Washington's Bradley Beal said. "When you have a team like that - guys who, a lot of them weren't on the team last year, weren't on the team early in the year. Guys who don't have deals; they're hungry. They want to play and they're taking advantage of their opportunity and kicked our (butt)."

Markkanen nailed five 3-pointers, including a key shot beyond the arc in overtime. Dunn hit two 3's in OT, and converted a pair of free throws near the end to make it a six-point game.

Jabari Parker led Washington with 28 points against his former team. Beal scored 27 and hit the tying jumper in the closing seconds of regulation. But the Wizards went 0 for 6 from the field in OT, losing for the third time in four games.

"They didn't get a field goal?" Dunn said. "That's what I like to hear. That's what I like to hear. Great team defense."

Tied at 113 through four quarters, the Bulls went on an 8-2 run to start overtime, with Robin Lopez hitting two foul shots and Dunn nailing two 3-pointers. It was 121-117 with a minute left when Dunn missed two free throws.

Beal then missed the first and made the final two free throws after getting fouled on a 3, cutting the lead to two. But Markkanen nailed a 3 from the top of the key to make it 124-119 with 32.3 seconds remaining.

Parker then put up an airball on the second attempt after making the first free throw, and Dunn hit two foul shots to make it 126-120 with 19.5 seconds left.

GOING TO OT

The game was the second between the teams since the deal that sent Porter to the Bulls for Parker and Bobby Portis on Feb. 6. The Wizards beat the Bulls 134-125 three days later in Chicago, with Beal scoring 31.

This one went to overtime after Beal hit a baseline jumper to tie it with 2.4 seconds left. Markkanen then inbounded to Robin Lopez at the top of the key following a timeout. The Bulls wanted their star to get the ball back, but the Wizards took away that option.

Lopez was unable to get a shot off before the buzzer, sending the game to overtime.

OUCH

Markkanen insisted a blow to the face he took from Portis in the final minute of regulation while trying to score down low was unintentional.

Markkanen made two free throws to extend the Bulls' lead to 112-109 with 50 seconds left. Portis got called for a flagrant foul.

"I actually haven't seen the play yet, but I don't believe it was intentional," Markkanen said. "I don't think he's like that. The thing about Bobby is that he just always plays so hard so stuff happens."

TIP-INS

Wizards: Portis had 15 points. ... Parker has 10 straight games with 15 or more points.

Bulls: Porter missed his second consecutive game. Coach Jim Boylen said an MRI showed no structural damage, but was not sure when his player will return. Porter expects to return this season from the injury, which occurred during the game at Sacramento on Sunday.
